To all 'whom #may concern.'

Be it known that I, 'FREDERICK A. BRUNS, a citizen of the United States, residing at Blaine, in the county of Whatcom and State of Washington, have invented a certain new and useful Improvement in Separatore, of which the following is a specication.

' My invention relates to. improvements' 1n separators lfor washing sand, gravel and the like 4and the object of my invention -is to provide a separatorv that is simple in its plan"of construction and efiicient in its operation. r

A further object is to provide a separator wherein the material that is being washed is. permitted to drop by gravity through passageways through which Water is caused to iiow upwardly in such manner that the water will serve to thoroughly wash the san or gravel. and to remove therefrom any particles of lighter material, as pine needles, chips of Water soaked wood and the like.

Other and more specific objects will be apparent from the followingdescriptio taken in connection with the appended claims.

I accomplish these objects by devices illusin the accompanying drawings, wherein- Figure 1 is a view in vertical section substantially on broken line 1, 1 of Fig. 2

of a separator constructed in accordance with my invention;

Fig. 2 is a view in vertical cross-section of the same substantially on broken line 2, 2 of Fig. 1;

Fig. 3 is a view in cross-section of a detail of.my invention; and

Fig. 4 is a view in cross-section on broken line 4, 4 of Fig. 3 certain being shown in plan.

Y Referring to the drawings throughout which like reference numerals indicate likeparts, the numeral 5 designates a rectangular box having a top side comprislngva fixedly mounted inclined portion 6, a rigidly mounted horizontal portion 7 and a swingingly mounted door 8.l

Disposed between the door 8 and the horizontal portion 7 are suitable frame members 10 that form a receptacle for supporting a removable block 11.

The block 11 is provided with a plurality of transverse triangularly-sha ed stri s 12 that are. removably secured tot e top side of such block and are arranged in spaced apalt.

parts of which is to be washed.

Disposed upon the triangular strips 12 and arranged to be moved transversely of the block l1 to agitate the sand or gravel that falls upon such block 1l is a grating or )igger l5 that is provided at each of its opposite ends with an upwardly projecting bar 16 that is connected by links 17 with eccentric pins 18 on disks 19 that are secured to opposite ends. of a transverse vshaft 2O so that 'when' the shaft 2O is rotated by any suitable 'source of power, notl shown,fthe jigger.l .15 will be reciprocated on the block 11. Y-

Spaced above the block 11 and adjustably mounted in grooves 21 lin upright members 22 are a plurality of slats or distributing bars 23 that form an adjustable grating whereon material and water may be. delivered from a chute 24. The chute 24 is means of bolts 25 which pass through slotted 'holes 26 in the sides of the chute 24 and through slotted holes 27 inthe upwardly ported by brackets 31 having bolts 32 that pass through slots 33 in theends 28 of the box 5, the block 30 being adapted to be moved up or down the inclined' top portion of the perforated block 11. f

Disposed below thel perforated block 11 and ext/ending lengthwise thereof are a plurality of jetting devices indicated generally by the numeral 34 each of which jetting devlees comprises a relatively long triangularly-shaped receptacle that is provided inv its top side 'or apexvwith perforations and in itsbottom with an arcuate. wall 36 that dividesthe interior of the jetting devices into an upper compartment 37 and av l" i 6 t0 regulate the ldepth of water on the top* endV with apipe 40 lwhich in turn is con-v may be stored.

nected by a T-ttng 41 with a vertically arranged pipe 42 that is rovided with a valve 43 and is connected with a larger hori-l zontal pipe 44 that communicates by means of a pipe 45 with a tank 46 wherein water may be evenly distributed throughout the.

length of the chamber 37 and will issue with equal force from all of the perforations 35.

The jetting devices 34 are positioned so that the perforations 35 are directly below the perforations 14 in the block 11 whereby,

water that is emitted from the perforations 35 will be jetted upwardly through the perforations 14 in the block 11 at the same time that sand or gravel is passed downwardly through such perforations thereby serving to thoroughly wash the sand or gravel and to prevent any particles of lighter material from passing downwardly into the box 5.

By maintaining a substantially constant height of water in the tank 46 it is possible to maintain a substantially constant pressure within the chambers 37 of the jetting devices, the water from" the tank 46 eing distributed by the4 relatively large pipes 44 with substantially equal pressure to all ofthe pipes 42 and such water being distributed by means of the perforations of graduated size in the` arcuate wall 36 at substantially constant pressure to the chamber 37.

Disposed above the block 11 and adjacent the rear edge thereof is a perforated water pipe 50 that may be used for spraying water upon the top of the perforated block 11 if desired.

The distributing bars 23 are adjustable so that the spaces therebetween may be varied to grade and evenly distribute the materials that fall on the blo'ckll. 'In practice the bars 23 will ordinarily be closer together at the point where the material comes on to such bars and will be spaced at gradually. v increasing distance toward the discharge end thereof so that the larger material' will be carried over to a point near the discharge edge of the block 11 before it is dropped on such block. -f

Sand or gravel and water may be delivered by a spout lfinto the chute 24 and maybe discharged therefrom on to the distributng'bars 23.

As the sand and water passes over the chute 24 the sand or gravel will tend to settle in the bottom of such chute While the water will tend to flow on top thereof, and, for the purpose of removing the surplus water, if more water than is needed for washing the material, is passin over the chute 24, I

. have provided a re atively shallow pan or chute 52 having its u per end adjustably secured by means of a golt 53 andslot 54 to the end of the chute 24and its lower end adJustably secured by means of a bolt 55 and slotted link 56 to the upper portions 28 of the end walls of the box 5.

The box 5 is provided in its opposite ends with transparent plates or windows 57 through which the accumulation of sand therein may be observed and which further enables the observer to determine whether or not the water in the box is clear or muddy to thereby determine whether or not the sand is being thoroughly washed.

The box 5 is provided at one or more points with openings 58 that are adapted to be closed vby slides 59 and through which washed sand or gravel may be removed.

In the-operation of my device the sand or gravel together with a considerable amount of water is delivered from the trough 51 into the chute 24 thence passes downwardly onto the distributing bars 23, 'the excess water bemg taken olf over the pan 52, the sand will drip downwardly between the bars 23 on to the top of the block 11 where it will beagitated and kept moving by the upward current of water emitted through the perforations 14 and, by the reciprocating movement of the jigger 15..

All of the particles of sand and gravel will eventually pass downwardly through the perforations 14 while the lighter materials as fioating chips, pine needles, clay,

vdirt and the like will be washed away by the the chute 24 so `that no pieces that are too large to ass through the perforations 14 will be delivered on to the block 11.

In instances where a constant stream of sand or gravel is delivered from the chute 51 it may be advantageous to employ two or more of -my separators so that the flow of sand or gravel may be directed into vone separator while the washed material is being removed from the other.''

'It will be obvious that changes in the recise form of construction of the varlous parts of my invention may be resorted/to within the scope of the following claims.

What I claim is:

' 1. A separator of the class described comprising ar'eceptacle; a perforated b1ocksup ported in the top side of said receptacle; an

-agitator reciprocable on the top side of said block; a grating arranged above said block.

to distribute material evenly over said block; a chute for 'delivering water and mfaterial to 'be washed on to said grating; and

^ in said block.
